Commercial Mortgage Interest Rates
Interest rates vary between lenders based on their view of the risk profile of your business. Lenders have their own risk appetites and scorecards, but a helpful way to get an idea of what interest rate your business could get is to think in terms of “risk bands”:
- Risk band A: Strong personal credit score, strong business credit score, trading for 5 years or more, good profits, good balance sheet net worth. Low loan to value.
- Risk band B: Reasonable personal score with only minor issues, reasonable business credit score, trading for 2 years or more, profitable. Higher loan to value.
- Risk band C: Some recent credit issues or weak credit score (missed payments or satisfied CCJs)
In addition to working out which category you’d fit into, lenders will also price your loan very differently depending on the type of property being funded, as well as the loan to value. The higher the loan to value, the higher the interest cost.
So you could expect rates as follows:
- Risk Band A: 6%-8% p.a. fixed for 5 years. Alternatively 2%-3% above base rate. These rates would typically be available with high street lenders and some specialist lenders only available through commercial mortgage brokers.
- Risk Band B: 7%-9% p.a. fixed for 5 years. Alternatively 3%-4% above base rate. These rates tend to be available via challenger banks and some specialist lenders.
- Risk Band C: 8%-10% p.a. fixed for 5 years. Alternatively 4%-6% above base rate.
These rates are annual, and are for illustration only.
